Note: Clean the filter at least every 4 weeks to ensure that it continues to filter

Descaling
The sterilization process is extremely important to ensure the most hygienic standards
for your baby. Limescale deposits can slow down the sterilization cycle and even
impair its effectiveness.
Limescale is the hard and chalky deposit. Depending on the water type in your area,
limescale can have different appearances ranging from snow white looking powder
to brownish stains. The harder the water, the faster scale builds up. It builds up in
appliances as the residue of minerals naturally contained in water, which fail to
evaporate when water is heated. Although it is not harmful as such, it is unsightly, hard
to clean and can impair the operation of appliances or damage their components if
allowed to build up.
Descale the sterilizer at least every 4 weeks to ensure it works efficiently.
